Each topper is solid on one end for chewing, hollow on the opposite end to conveniently fit over standard #2 pencils, and textured all around for extra tactile input. The front side features large bumps, with small bumps on the back side for varied sensory input. Each topper measures about 2.5" long, .6" wide, and .5" thick and comes with an eraser-less pencil
Available in 3 color-coded toughness levels:
Standard - This is the softest level, recommended for mild chewers (those who do not chew through anything).
XT / Medium Firm - This is the middle level, which we call XT ("Xtra Tough"). It's firmer, but still fairly chewy, recommended for moderate chewers.
XXT / Very Firm - This is the toughest level, which we call XXT ("Xtra Xtra Tough"). It still has some "chewability" to it, but it’s fairly rigid / pretty firm. No chew tool is indestructible, but this is usually the longest lasting level for avid chewers.
